Subject: [PATCH AUTOSEL 6.6 16/21] spi: cs42l43: Handle error from devm_pm_runtime_enable

From: Charles Keepax <ckeepax@...nsource.cirrus.com>

[ Upstream commit f9f4b0c6425eb9ffd9bf62b8b8143e786b6ba695 ]

As it devm_pm_runtime_enable can fail due to memory allocations, it is
best to handle the error.
